Solar Module Frame With Sliding Fixing Member for Rafter Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar battery modules face issues with misalignment between joint portions and rafters, leading to weakened fixing strength and increased costs due to complex machining requirements and differing shapes of eaves-side and ridge-side frame bodies.
Innovation Solution
A solar battery module frame body with a sliding fixing member that can be aligned with rafters, featuring connecting and movement-restricting mechanisms to ensure strong fixation and reduced labor, while using symmetric shapes to minimize parts and molds, allowing for adjustable height and enhanced ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If joint portions are integrally provided on frame bodies for mounting on roofboards, then the solar battery module can be directly mounted on roofboards, but the joint portions cannot be aligned with rafters when rafter positions and joint portion positions are not aligned, resulting in deteriorated fixing strength
Solution Approach 1:
The fixing member is designed to be movable along the first frame body, allowing it to dynamically adjust its position to align with rafters during installation. This dynamic positioning capability enables the fixing member to adapt to varying rafter positions while maintaining strong fixation, resolving the contradiction between ease of manufacture and fixing strength.
Solution Approach 2:
The fixing function is separated from the frame body by introducing a独立的 fixing member that can move independently along the frame body. This segmentation allows the fixing member to be positioned optimally at rafter locations while the frame body maintains its structural integrity and manufacturing simplicity.
2Adaptability or versatility
If eaves-side and ridge-side frame bodies have different shapes to accommodate joint portions, then mounting functionality is achieved, but complicated machining operations are required and costs increase
Solution Approach 1:
The first frame body is designed with a standardized shape that can serve multiple functions: supporting the solar battery panel, providing a sliding path for the fixing member, and enabling connection to adjacent frame bodies. This universal design eliminates the need for different shaped eaves-side and ridge-side frame bodies, reducing manufacturing complexity while maintaining mounting functionality.
Solution Approach 2:
The mounting functionality is extracted from the frame body and transferred to the fixing member. The frame body is simplified to only provide structural support and a guide path, while the fixing member handles all mounting and positioning operations, including adaptation to different rafter positions.
3Ease of operation
If fixing members are fixed at specific positions on frame bodies, then installation is simplified, but the fixing members cannot be aligned with rafters when positions do not match, reducing fixing strength
Solution Approach 1:
The fixing member is designed with movable capability along the first frame body, allowing installers to dynamically position the fixing member at optimal locations that align with rafters during installation. This dynamic positioning maintains both installation simplicity and fixing strength by enabling adaptation to actual rafter positions.
Solution Approach 2:
The fixing member is pre-equipped with sliding capability and connection interfaces before installation, enabling it to be easily moved and positioned during the installation process. This preliminary preparation allows for quick alignment with rafters without complicating the installation procedure.
4Adaptability or versatility
If multiple different frame body shapes are used for eaves-side and ridge-side, then specific mounting requirements are met, but the number of parts and molds increases, raising costs
Solution Approach 1:
A standardized first frame body design is used throughout the solar battery module structure, serving multiple functions including panel support, fixing member guidance, and inter-module connection. This universal frame body design reduces the number of different parts and molds needed while maintaining the ability to meet various mounting requirements through the movable fixing member.
Solution Approach 2:
The functions of different shaped eaves-side and ridge-side frame bodies are merged into a single standardized frame body design combined with a versatile fixing member. This consolidation reduces the total number of unique parts required while maintaining all necessary mounting capabilities.

AI summary
A fixing member (3, 40, 43, 50, 53) which fixes a first frame body (1) of a solar battery module main body (9) slides along the first frame body, and the solar battery module main body includes a connecting portion (10) and a to-be connected portion (11) which connects the first frame bodies which are adjacent to each other through the fixing member. With this, a position of the fixing member can freely be moved with respect to the first frame body, the fixing member is slid to a position where there is a structure member (32) which supports a roofboard at predetermined intervals, and the fixing member is mounted at that position. With this, the fixing member can be mounted more strongly, and the adjacent two first frame bodies (31) can be fixed by the fixing member.
